HYDRAULIC PRESS FOR THICK FLUID SUBSTANCES SPECIFICATION forming part of Letters Patent No. 708,180, dated September 2, 1902. Application filed February 24, 1902. Serial No. 95,467. (No model.)

To a/ZZ whom, t may concern,.-

Be it known that I, GOTTFRIED voN Sss- KIND, a citizen of Germany, residing in St. Georgen, near St. Gallen, in the canton of St. Gallen, Republic of Switzerland, (whose post-office address is St. Georgen, near St. Gallen,) have invented certain new and useful Improvements in Hydraulic Presses for Thick FluidSubstances; and I do hereby declaro the following to be a full, clear, and exact description of the invention, such as will enable' others skilled in the art to which it. appertains to make and use the same, reference being had to the accompanying draw ings, and to figures of reference marked thereon, which form a part of this speciiication.

I have applied for patents in the followingv countries: application in Switzerland` on August 14, 1901; applicationin Francebn September 14, 1901; application inA Germany on September 16, 1901; application in Italy on September 16, 1901.

The object ot' the present vinvention is a hydraulic press for/thick tluid substances, one form of construction of which is illustrated by way of example in the accompanying drawings, in which- Figure 1 is a vertical section through the center of the press. Fig. 2 is a plan view of the same. Fig. 3 is a horizontal section on the line o: @c of Fig. 1. Fig. 4 shows a horizontal section of a plate which can be heated by steam. Fig. 5 shows a vertical section of a portion of Fig. l on an enlarged scale.

Upon the table 2, supported on standards 1, are screwed two strong posts 3 4. On the former ispivoted the center piece 5 of the receptacles 6 7, which together form one piece.

In the position illustrated the receptacle 7 rests with a projecting edge 10* over an aperture 9 in the table 2, which aperture is de# vised to receive a mold 8. 1u order to enable the two receptacles to be raised from the table, there is placed on the post 3 a doublewalled cylinder 10, which is closed at the top and the cavity 13 ofwhich'is closed at the bottom by a packing 1l. Set-screws 14 l5 in the latter-and support-ed on the table allow ot the correct moving up of the receptacles. The cylinder l0 has, moreover, a perforation 12, which communicates, on the one hand,

with the pressure-water tube 18 and, on the other hand, with the hollow chamber 13. By passing the pressure-water into the hollow chamber 13 the cylinder l0 is raised, where-` Athat receptacle 6 takes the place of receptacle 7, and vice versa. Stops 16 17, placed on the two receptacles 6 7, by striking against the post 4 limit the rotation of the receptacles. An angle-bar 18, placed on the stop 17, and a ball-bearing 55, set between the center piece 5 and cylinder 10, enable the rotation to be easily effected by hand.

On the upper part of the posts 3 4 is set another pressure-cylinder 19, with piston 20, to which is linked a compressor 2l of corresponding section to the receptacles 6 7. Into the bore of the cylinder 19 the pressure-water tube 22 discharges, so that the piston 20 can be loweredby hydraulic power. To the top of the post 3 is pivoted a revoluble support 23, on the horizontal arm 24 of which are arranged two spindles 25 26, provided with screw-threadings which bear a piston 27, corresponding to the aperture of the receptacles 6 and 7. Between the two spindles 25 26 is arranged a fixed axle 28, on which the iiy-wheel 30 revolves. The hub of the latter bears a wheel 3l, which engages in two gear-wheels' 36 37, placed on the matrices 34 35, revoluble in the bearings 32 33 for the spindles 25 26, so that by suitably revolving the fly-wheel 30 the piston 27 can be raised or lowered. In the position illustrated the receptacle Gis closed below by a bottom piece 3S, which is arranged in a support 4l on a screw-threaded spindle connected by a nut 40 with a fly-wheel 39.

The method of operation is as follows: 'The mass tobe pressed is placed in the receptacle 6, the support 23 having been previously 'rotated about ninety degrees, thus rendering the receptacle leasily accessible. Then by turning the ily-wheel 30, and the consequent lowering of the piston 27, the mass is so strongly pressed that after removing the bottom 38 it remains in the receptacle. After this the pressure-water is introduced through IOO the pipe 1S into the bore 13 of the cylinder 10, and thereby the two receptacles are raised until the edge 10* comes out of engagement with the table 2. By means of the bar 18 the filled receptacle 6 is then turned above the aperture 9 in the table, so that after letting olf the water which was introduced into the cylinder 10 it takes exactly the position formerly held by the receptacle 7. By introducing the pressure-water into the cylinder 19 the piston 20, with the compressor 21, is made to descend, and thereby the mass in the receptacle 6 is pressed through the mold 8. Vthilc the compressor 21 is sinking in the receptacle 6, the receptacle 7 can be charged in the manner described above, so that continual working is possible. In order to prevent the two receptacles being lifted off the table by the pressure of the compressor 21, the two posts 3 4 are provided with screwthreadings 43 44 and nuts 45 46, which can be engaged by rotating a vertical bar 48, provided with a handle 47, from which bar the movement can be transmitted to the nuts 45 4 by means of levers 49 50 51 and 52 53 54, respectively, and thereby fix the central part 5 and stop 16 or 17.

The mold 8 (shown in Figs. 3 and 5) is adapted for making macaroni.

On a heel 55:5 of the funnel 56, which widens out toward the bottom, is a grating 57, strengthened by transverse bars. On this grating rests a bipartite metal plate 42, the outer form of which corresponds to that of the grating 57. In the walls of each plate, as also in the ribs thereof, are two series of superposed steam-passages 59 60, the upper series communicating with the lower by means of a number of apertures 61 62. If now steam is introduced through the two pipes 63 64 and let out again through the pipes 65 66, the two plates are uniformly heated and receive the mass pressed through the mold warm and malleable. Above the metal plate 42 is the plurallydivided mold S, which has a number ot holes, each corresponding in size to the section of the macaroni. By means of screws the mold is secured to the metal plate 42. The receptacle presses with its lower edge upon the mold and assists in maintaining the same in the recess of the table.

IVhat I claim is- 1. In a hydraulic press for thick duid masses, rotatable receptacles, a divided mold in communication with said receptacles, means for lifting the said rotatable receptacles out of a recess in the table, mechanism for adjustably securing the receptacles to their support, and means for heating the mold and the substances under pressure.

2. In a hydraulic press for thick fluid masses, rotatable receptacles, a plurally-divided mold placed in the table and secured in position by the receptacles and screws, a hydraulic pressure device concentric to the aXis of rotation of the receptacles and adapted to lift the rotatable receptacles out of the recess in the table, means for adjustably securing the receptacles to their support, a perforated heating-body havinga system of passages and placed beneath the mold for heating the same and the substances under pressure.

3. In a hydraulic press for thick fiuid masses, in combination the posts 3 and 4, the center piece 5 the receptacles 6 and 7, the mold 8, the funnel 56, the plate 42, the gratu ing 57, the steam-passages 59 and 60, the inlet-pipes 63 and 64 the outlets 65 and 66, mechanism for raising said receptacles 8 and mechauism for adjustably securing the receptacles to their support.

In testimony that I claim the foregoing I have hereunto set my hand this 11th day of February, 1902.
